Half of the bovine Escherichia coli (E. coli) strains with the intimin gene (eae) were classified into potential enterohemorragic E. coli (EHEC), since the strains were serotyped into several major O-serogroups of EHEC with public health importance. An eae gene was considered an important epidemiological marker for screening EHEC from cattle fecal samples. (Clinical Epidemiology Section, Department of Epidemiology TEL +81-298-38-7798)
